Electrocatalysts for hydrogen evolution and CO2 reduction derived from earth-abundant metalsmay one day provide an efficient and economical means to fuel production. Compatibility witheither organic or aqueous conditions is of interest in developing such catalysts for practicalapplications. We have previously demonstrated that iron carbonyl clusters can catalyze CO2reduction to produce exclusively formate in MeCN solution. This reaction occurred in thepresence of protons and the reaction conditions were controlled to prevent significant hydrogenevolution. In this presentation I will describe the synthesis and characterization of a series ofnew iron carbonyl clusters that have been designed to modulate the interaction of the clusterswith both protons and CO2. I will describe the effect of the cluster modifications on both CO2and proton reduction as observed using electrochemical measurements. The pH dependenceof the reactivity will be discussed along with electrochemical measurements in organic solutionwhich have allowed for additional mechanistic insight into the reactions.
